Why is my device not recognized when I log in to LastPass?
The security of your LastPass account is our highest priority. If we detect a login attempt from an unidentified location from any new computer, mobile device, or new IP address, we want to verify that it's really you logging in to access your LastPass vault. To do so, a verification email is sent to the LastPass account email address (or Security email, if you have set one up) that contains a link you can click on to verify that it's you.

How do I verify my device as trusted?
Check your email inbox for an email from LastPass about your login being blocked. If you received this email and are logging in to LastPass from a trusted device or location, click the verification link within the email, then log in to LastPass again.
I checked my email but I didn't receive an email from LastPass. Where is it?
If you have set up a Security email address, please check that inbox as the email was sent there. Also, please be sure that you have added do-not-reply-support@lastpass.com as contacts and to your email filter's allowlist, then prompt LastPass to send you another verification email.
What if I don't have access to my email address?
If you cannot access your email inbox but have permitted offline access in your account, you can log in offline to get a cached version of your LastPass vault. Otherwise, you will need to recover access to your email address via your email provider, then prompt LastPass to send you another verification email.
What if the email address I used no longer exists?
If you need additional assistance, pleasecontact LastPass Support by selecting Contact Support within this article.
Once you have regained access to your account, be sure to update your account email address.
Once verified, how do I disable email verification?
You can disable the email verification requirement completely for your LastPass account.
